A second Russian athlete has failed a doping test at the Pyeongchang Games, a day before the International Olympic Committee's executive board is to decide whether to reinstate the country for Sunday's closing ceremony.

Russian Bobsled Federation President Alexander Zubkov told the Associated Press on Friday that a drug-test sample that pilot Nadezhda Sergeeva gave on Sunday was positive.

The Russian delegation at the Pyeongchang Olympics said in a statement that the substance found was trimetazdine, a medication used for angina sufferers that is listed by the World Anti-Doping Agency as a banned substance affecting the metabolism.

When she arrived for the Winter Olympics in South Korea, Chloe Kim already was an accomplished snowboarder with a handful of endorsement deals from the likes of Visa Inc., Nike Inc. and Toyota Motor Corp.

Then came her dominating performance to win the gold medal in the women's snowboarding halfpipe in Pyeongchang, and the charismatic 17-year-old Southern Californian instantly became a breakout star of the Olympic Games with a future likely to include much more lucrative sponsorship deals.

Alina Zagitova has won the women’s figure skating competition, becoming the first Russian gold medalist at the Pyeongchang Olympics.

The 15-year-old Zagitova edged her friend and training partner Evgenia Medvedeva to end the gold drought for the Olympic Athletes from Russia. That’s the designation given to the nation’s competitors after Russia was officially banned by the IOC for a doping scandal.

Zagitova and Medvedeva tied in the free skate, a rare occurrence, but Zagitova had won the short program Wednesday, so she got gold.

The Americans secured their worst showing in modern-era Olympic women's figure skating with Mirai Nagasu failing to get any lift on her triple axel and popping a triple lutz.

The 24-year-old Nagasu was fourth at the 2010 Vancouver Games but never got going in the individual competition at the Pyeongchang Games after helping the U.S. win a team bronze. She hit her triple axel in that event, becoming the first American woman and third overall to do so in an Olympics. But she slipped below U.S. champion Bradie Tennell in the standings after Friday's free skate, with 2017 national champ Karen Chen just behind.

Tara Lipinski and Johnny Weir will be there. So will Ivanka Trump. And very likely so will at least one K-Pop star, as well as many of the athletes we’ve grown to know and love during the two-plus weeks of the Pyeongchang Winter Olympics.

But the majority of us will not be at this weekend’s closing ceremony in South Korea. Lucky for us, though, there’s several opportunities to watch.

Anyone who feels the need to watch the event as it unfolds Sunday at 3 a.m. Pacific time can do so at NBCOlympics.com or by using the NBC Sports app. Those who prefer to be well rested while they watch can tune in to taped broadcasts of the ceremony on NBC at 5 p.m. and again at 8 p.m.

Dutch speedskater Sven Kramer has issued an apology after he and several teammates accidentally injured two fans by throwing a giant replica of a bronze medal into a crowd during a promotional event at the Pyeongchang Olympics.

Kramer won his third straight Olympic gold medal in the 5,000 meters earlier in these Games. He and teammates Jan Blokhuijsen, Patrick Roest and Koen Verweij also won bronze in the team pursuit, bringing Kramer’s career Olympic medal count to nine.

Those four speedskaters were onstage at an event held at the Heineken House on Wednesday night when they received a giant replica of their bronze medal and somehow thought it would be a good idea to toss it into the crowd.

The United States will compete for a gold medal in men's curling after knocking out their Canadian opponents 5-3 in a tense semifinals showdown at the Pyeongchang Olympics.

The U.S. victory on Thursday is a remarkable turnaround for a team that hasn't made the Olympic podium since the 2006 Turin Games, when they won a bronze medal.

Just as remarkable was the loss for Canada, which has won the gold medal in men's curling at the last three Winter Olympics. The Canadian women's team, meanwhile, didn't even make the semifinals, despite being the defending world champions.
